"The Senate language is a significant departure from current law and is unacceptable," said Stupak. "While the President has laid out a health care proposal that brings us closer to resolving our differences, there is still work to be done before Congress can pass comprehensive health care reform."
Stupak drafted language in the House version of the health reform bill -- the so-called Stupak amendment -- barring coverage of abortions in government-run health care plans and keeping people who get federal health subsidies from purchasing plans that provide coverage for abortion.
The House health care bill would likely not have passed without the Stupak amendment, which attracted the support of 64 Democrats when it came up for vote.
While the Senate and White House plan bans direct funding of abortions, it allows subsidized individuals to pay for covered abortion services with personal funds.
Meanwhile, according to Politico's Mike Allen, there are currently not enough votes in the House or Senate to pass a health care reform bill.
"Moderate and endangered lawmakers want the spotlight off comprehensive health reform," he writes. "Instead, it's about to take center stage."
